* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-3/+3
| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

* Remove useless #ifndef in atc(6) and pom(6).fcambus2016-12-011-5/+1
| | | | | | M_PI is always defined, so we can drop those directives. OK deraadt@, millert@

* Prefer fseek(3) over rewind(3) since the latter although it also calls fseekmestre2016-03-161-3/+5

* - General changes:mestre2016-03-072-12/+6
| | | | | | | | | | | | - Remove -? from getopt(3) options, but still keep (or add) -h where applicable - Replace hardcoded program strings by getprogname(3) - Specific changes: - atc(6): this used -? and -u for usage(), remove both from game and manpage - bcd(6): use __progname instead of getprogname(3), no need to include stdlib.h - hunt(6): replace fputs(3) by fprintf(3) OK tb@ after his suggestions

* Some basic code maintenance in games/tb2016-01-071-3/+3
| | | | | | | | | | - in main() replace exit with return - drop some /* NOTREACHED */ lint comments along the way. - make more use of standard CFLAGS, esp. -Wimplicit-function-declaration - add and sort some headers when needed - add straightforward pledges to some programs used at compile time discussed with and ok mestre@
* About 13 years ago when the idiom srandom(time()), and sometimesmestre2016-01-031-2/+1
| | | | | | | | | | | | srandom(time()+getpid()), was changed by srandomdev(), but #include <time.h> lived up until this day so remove it. Additionally, earlier than that, 18 years ago, random(6) was one of the first consumers of arc4random(3) family, and was pulling it from dev/rndvar.h but these days we pull it from stdlib.h, which is already done, so while here remove dev/rndvar.h also. "seems comprehensive to me" deraadt@ and OK tb@

* Replace 'arc4random() % range' by 'arc4random_uniform(range)'.tb2015-12-151-5/+14
| | | | | | | | | | Do this by introducing atcrandom_uniform(range) which returns deterministic randomness or good randomness depending on whether a seed was specified with the -r option. Diff by Matthew Martin, reviewed by deraadt@ and me. ok deraadt@
* adjust width list: Ds is unfortunate here;jmc2015-11-291-2/+2

* Add pledge support and move score file to $HOME.tb2015-11-294-33/+40
| | | | | | | For high score entries use the same logic as in snake(6) and tetris(6): Try LOGNAME then USER then getlogin(2) and fall back to ???. For variety, atc(6) uses flock(2), so add a "flock" promise to the usual "stdio rpath rpath cpath tty" for games.

* In 1995, all of the games were setuid games. At end of 1996, I took them allderaadt2015-11-241-2/+1
| | | | | | | | | to setgid games, and we started wittling them down. Nearly 10 years later I am removing all setgid from the games. If any of these have score files they are now broken, and I hope various folk repair them. I have argued for years (and received pushback...) that the score file features must be removed, or rewritten to use private files, because setgid is the wrong tool. ok tedu
